The Latest on a former airman who had a sexual relationship with a 14-year-old. (all times local):

5:30 p.m.

A former airman who received an honorable discharge from the Air Force despite acknowledging he had a sexual relationship with a 14-year-old has been sentenced to five years in federal prison on child sex charges.

Nicholas Murphy was sentenced Wednesday afternoon. He pleaded guilty in June to federal charges of traveling from Rhode Island to Plainfield, Connecticut, in 2015 to have sex with the girl.

Prosecutors say Murphy avoided a dishonorable discharge by convincing the Air Force that he believed the teen was at least 16 years old.

But authorities cast doubt on that story, saying the two communicated over Facebook, where the teen's page included her actual date of birth. They say she also had sent Murphy a message about being excited to start the ninth grade.
